I just noticed today that my new Guinea Pig, Cookie, right eye keeps closing. Sometimes she will close it half way and then open it again. I just got her on Friday and she is only 4/5 weeks old. I am aware this behavior usually is a sign of an eye injury and I called the vet, and they were booked up until Thursday. Do you think that is too long to wait? I don't want her to get an infection. I'm very scared of this because I used to have a Guinea Pig named Peanut and she died after getting an injury to her eye by her hay. I do not want the same thing to happen to Cookie.
